Clarification of Dry Fire #'s

[Ucsdryder]

Super scientific. I've shot them all on 6.5 bitch biscuit 20", 22 creedmoor 20", .223 18". I've compared the Scythe, og30 and tracker on a 22" 300 WM. Strictly bro science from me.View attachment 1063734
I let my 7 y.o. rattle can his .223 how he wanted. Today was the maiden voyage for the "Merica paint.

Still curious to hear how the zg30 handles recoil. Nobody wants to talk about it. Just argue over noise!

Yeah, I am hoping that huge test they completed a few weeks ago sheds light on that subject. Seems like once you are actually around 130ish db, the recoil mitigation factor might play a big role in selection for non-homo cartridges.

How far away does someone think they can hear a dry fire?

Ideal conditions, 95% rh, 35 degrees, zero wind.

I don’t think that’s a valid question if you’re asking it in the light of “is it really 120db”. I’m not saying it is or isn’t 120 db. There is more to sound than just the db numbers. For example, someone can be shooting a suppressed rifle on your patio, and it’s hardly noticeable inside your house, but yet would still meter at 140 db. You can also have some drive up on your gravel drive, and you can hear that from inside the house. Doesn’t mean driving on gravel is 140 db tho. The sound travels differently, or impacts differently. Does that make any sense?

I would assume it depends on the “tone”…

I think you are now referring to the direction of the sound waves.

I was just asking how far anyone thinks it would carry.

Today I was hearing my guard dogs bark, at close to a mile away. It was 70 degrees and I think around 38-40 rh. Not great conditions for sound travel. Just got me thinking on sound over distance.

Dogs aren't supposed to be 120, I'm sure some can be. No idea what mine are.

Yeah, not saying my comment was accurate. I was even hesitant to participate in this dumpster fire

The correct term is frequency.

 

[Ucsdryder]

The correct term is frequency.

The experts use “tone”

 

[nm.otter]

It's frequency, and energy, and time -- 4D. The resonant frequencies and damping properties of the windows and the house walls, just to look at one small component of that picture.

Anybody ever metered a fart at the muzzle, and again at smellers ear?

Mine have on occasion been louder than a dry fire.

They are a lower frequency, the tone makes them carry further than their respective db level usually would.

Tho, some subsonic hit a magical tone, they are quite often completely silent to the human ear, and the contents move at a crawl, but can wipe out an entire room on occasion. Simply known as SBD's, silent but deadly.

Do we need Mythbusters on site to dispel the brown note theory?

We really over analyze every aspect of hunting and shooting. Especially supressors as I would bet 90+% of us have tinnitus to the point we can’t hear specific frequencies.

Also signal to noise. If it’s a relative quiet environment, sound can carry a long way and still be identifiable. Yet in a noisy environment, it won’t. Also if you have masking. Ie another sound that’s similar volume like wearing headphones and trying to hear things.
